Chemo- and Bio-Sensor Based on One Dimensional TiO2/SiO2 Photonic Crystals — •Anna-Katharina Hatz^{1, 2}, Ida Pavlichenko¹, and Bettina Lotsch^{1, 2} — ¹Ludwig-Maximilians-Universität — ²Max-Planck-Institut für Festkörperforschung

Photonic sensor technologies represent an important milestone in monitoring complex physical, chemical and biological systems. We present a new, biocompatible chemo- and biosensor based on the integration of an one-dimensional (1D) stimuli-responsive photonic crystal (PCs) with an electrophotonic visualisation platform. We demonstrate various modi operandi, including the measurement of the relative pressure of an analyte and the in situ monitoring of adhesive cell cultures, enabled by the modular combination of stimuli-responsive 1D PCs with a LED as light emitter and a photodiode as detector.
